Description
Other functions - active flow control (AFC) techniques hold considerable promise for improving rotor performance as well as for stall alleviation. In particular, previous 2-d oscillating wing experiments have demonstrated the potential of various AFC concepts to mitigate the effects of dynamic stall (improved lift and pitching moment characteristics). Unfortunately, many of these concepts (including zero mass flow jets) lose their effectiveness at higher (and more representative) mach numbers. NASA s goal is to understand the reasons for this loss of effectiveness and, more importantly, identify alternative concepts and control schemes that overcome these deficiencies. The objective of this effort is to design, fabricate, and evaluate a promising active flow control concept on an oscillating airfoil for on-blade alleviation of dynamic stall. The concept must be evaluated over a range of mach numbers (0.2 to 0.5) to substantiate the capabilities of the concept at representative mach number and/or identify reasons for the loss in effectiveness. Several values of reduced frequency shall be evaluated at each mach number tested.
